' the maximum economy-in cost' is combined with efiiciency and durability.

The invention consists in the novel construction and combinationsof devices illustrated in .the accompanying drawings and hereinafter described, and will be more fully pointed out in the appended claims.

of the several parts of In said drawings: I

Figure 1 illustrates my improved mat or cushion, asa whole, in a perspective view, partially broken away.

Figure 2 is a longitudinal, sectlonal view thereof, enlarged, the section being taken 1n the vertical lane indicated by the dotted line 2-2 on igure 1. V

Figure 3 is a transverse, sectional view of the same, enlarged, the section-being taken on the vertical plane indicated by the dotted line 3-3 on Figure 1. t

Figure 4 is a vertical, sectlonal view of a h 567118 t' e i res an are ers ec ive v1 ws gu abrih, detached, which are employed in the construction of my improved mat or cushion.

The cushion, indicated in Figure 1 as a I whole by the reference letter A, is composed of a plurality of pocketed sections having a spring S in each pocket. The sections will va-ryin length and number as may be neces sary to conformto the dimension of the completed article in which it is to be used, but for convenience in drawing and description, 1 have illustrated a six by six cushion, i. e. one using thirty six springs.

The fabric used is cut into appropriately sized pieces. The piece shown in Figure 5 is of a dimension to form the bottom 1 and two parallel sides 2, 2, of the cushion. The

piece shown in Figure 6 is folded so as to form one end 3 o the mat A, an interior wall 4 and an intermediate latter will constitute a part of the top of the completed cushion A. The piece shown in Figure 7 is L-shaped in cross section, the

portion 5, which part 6 constituting a portion of the top 01E the cushion A and the part 7 constituting an interior wall which will be parallel to the wall 4 when in assembled relation. The

' part 8 and-two bent ends 9. and

wall 7 of the end section of the cushion will however constitute the end wall of the cushion, opposite the end 3. g The piece shown in Figure 8 is folded so as to have a 10, the wall 8 constituting a division .wall, as will be explained. The several parts are secured together by hog rings 11 and by. stitching, as illustrate In constructing the mat or cushion A, the edge 12 of the wall 7 of is connected by stitches 13-to the edge 14 of the bottom 1, and its end edges 15 sewed to the edges 16 of the side walls 2. V

A number of the division strips 8, suitably one strip of fabric spaced apart,'are then sewed in to form a plurality of pockets, the ends 9 being sewed to the bottom 1 and the ends 10 to the top part 6 of the strip, as shown in Figures 1 and'3. A spring S is placed in each pocket thus formed.

The next strip 6'7 is then placed in 0- parallel to the wall 7 already positioned, c osing the spring filled pockets, the lower edge 12 being stitched to the bottom 1. Division strips 8 are similarly positioned in spaced apart. relation and sewed at their ends 9 and l() to the bottoin 1 and this second striptop 6, thus forming a second series .of pockets into each of Other section are similarly laid, pockets formed, springs. inserted and hog rings applied, until the cushion is ready for the last row of spring filled pockets. Then the strip shown in Figure 6 is used, the edge 17 of the partition wall 4 being sewed to the bottom 1, spaced apart strip: 8 positioned and sewed, t e top end 10 ing sewed to the top 5, springs S inserted in the pockets, and the bottom edge of wall 3 then sewed at 18 to the side edge 19 of the bottom 1. s

Hog rings 11 are used to clip the top coils of Sis-'placed. The vertical walls 7 of the two strips thus positioned are adjacent strips S, the wall 4, and the top 5 to the overla ping adjacent top 6. The line of stitches w ich secure the edges 15 to the edges 16 is continued across the top of the cushion A and secures the ends 20 to tops 6 and end 21 of top 5 to the top marginal edge 22 of walls 2 and also secures the end edge 23 of wall 2 to end 24 of wall 3.

The order of assembling and stitching the parts to ether, and of applying the hog. rings, as erein recited for convenient illustration, may, of -course, be varied as the skilled workman may desire, without departing from the essential idea of my invention, which is the use of the few partsdescribed and their assembly mm the com lete unit A.

I The cushion so formed presents a neat and finished a pearance, the springs are comletely enc osed in pockets by a single web of abric excepting onl where the top 6 and 5 are overlapped and 0g ringed as shown in Figure 4, and possesses the advantage of a strong, eflicient, durable andvery economical construction.

I claim as my invention:

1. A device of the character described consisting of a coiled spring-contained cellular casing, said casing com rising a rectangularly shaped iece of fa ric folded to form a bottom and two side walls, an inverted U-shaped fabric strip having its longitudinal margins connected to said bottom and extending from one folded side wall to the other, a plurality of inverted L-shaped places of fabric parallel to each other and to said U-shaped piece, one margin of the L'shaped pieces being connected to the bottom fabric, the free margin of one of said L-shaped pieces overlapping the U-shaped strip and the free margins of the other L-shaiped pieces overlapping an adjacent L-shape piece.

the various parts- 'cent L-shaped piece,

2. A device of the character described consisting of a coiled spring-containcd cellular casing, said casing comprising a rectangularly shaped piece of fabric folded to form a bottom and two side walls, an inverted, U-shapcd fabric strip havin its longitudinal margins connected to sai bottom and extending from one folded side wall to the other, a plurality of'inverted L- shaped pieces of fabric parallel to each other and to said U-shaped piece, one margin of the L-shaped pieces being connected to the bottom fabric, the free margin of one of said L-shaped pieces overlapping the U- shaped strip and the free margins of the other L-shaped pieces overlapping an adjathe two side walls being connected to the ends of the U-shaped and L-shaped pieces.

3. A device of the character described consisting of a coiled spring-contained cellular casing, said casin comprisingarectangularly shaped piece of abric folded to form a bot-,

tom and two side walls, an inverted U- shaped fabric strip having its longitudinal margins connected to said bottom and extendlng from one folded side wall to the 'other, a plurality of inverted L-sha ed pieces of fabric parallel to each other an to said U-shapcd piece, one margin of the L- shaped pieces being connected to the bottom fabric, the free margin of one of said L shaped pieces overlapping the U-shapcd strip and the free margins of the other L- shaped pieces overlapping an adjacent L- shaped piece, and short partition strips in said U-shaped and IL-shaped pieces.

In testimony that I claim the foregoing as my invention, 27th day of April, 1926.
